If you were supposed to get an email from the forum but didn't (e.g. to verify your account for registration), email Wes at stararmy@gmail.com or talk to me on Discord for help. Sometimes the server hits our limit of emails we can send per hour.
While you are new to the ship, include your character's name in your posts for the first few missions. Learning names is hard even in real life, so letting everyone know in your post who your character is a few dozen times will help everyone get to know your character and may even avoid them being ignored!
If you are waiting to board (as there is a current mission underway) and want to RP, writing solo past RP is fine with me! That is where you write your character on the ship before the current mission and what they are doing. There's a lot of easy reasons why your character wouldn't be involved in the current mission, so don't worry about the implications or consequences of them not being present for the current mission, just have fun and write :]
